PRODUCT INFORMATION
AVF 49xyA
Jan/2004
AVF 49xyA
Audio/Video Front-End
The AVF 49xyA is a fully integrated Audio-
Video Front-end solution specifically well
suited for DVD recorder and personal video
recorder (PVR) applications. It combines
the functional units of both a Multistandard
Sound Processor (MSP) and a Video Pixel
Decoder (VPX) and it provides the audio/
video synchronization of the output signal.
The AVF 49xyA comes in a PQFP128 pack-
age.
The MSP unit covers the sound processing
of all analog TV standards worldwide, as
well as the NICAM digital sound standards.
The full TV sound processing – starting with
analog sound IF signal input down to pro-
cessed analog AF signal output – is per-
formed.
The VPX unit provides the full-feature video
acquisition for consumer and multimedia
applications. All of the processing capability
necessary to convert an analog video signal
in CVBS, Y/C or YCrCb format into a digital
component stream is integrated. Addition-
ally, text slicing for Intercast, Teletext, and
Closed Caption is provided. For improved
Y/C separation, an adaptive 4H comb filter
is included.
